Japanese invasion of Manchuria

from 18 September 1931 to 27 February 1932

Japanese army officers of the Kwantung Army staged an explosion on a railway near Mukden, now Shenyang, in September 1931 and used it as a pretext to occupy the whole of Manchuria in north-eastern China. Chinese forces were told not to resist, and the region fell within months. Japan set up the puppet state of Manchukuo in 1932 with the last Qing emperor, Puyi, as its head. China appealed to the League of Nations, whose Lytton Commission found Japan to be the aggressor, and Japan left the League in 1933. The invasion showed the weakness of collective security in the 1930s and began a conflict that widened into full war between China and Japan in 1937.
